Sorry for the delayed response.
Other parameters that we have changed are in the section, ETH configuration -> Advanced Parameters -> Extended: External PHY configuration
and the values are as below
PHY Special Control/Status register Offset - 0x1F
PHY Speed Mask - 0x0004
PHY Duplex Mask - 0x0010
PHY Interrupt Source Flag Register Offset - 0x001D
PHY Link Down Interrupt - 0x0010
Its been a long time, I dont remember the basis for the above change. Good luck.
